Kenneth A. Smith wTe Corporation Bedford, Massachusetts The SEMASS waste-to-energy facility has employed the straightforward "Shred Burn" approach to Refuse Derived Fuel (RDF) production. The relatively trouble-free start-up seems to indicate that the design­ ers have incorporated the industry learning experience of the past 10 years. In this discussion, questions are raised relative to local p...

The paper will present available De-NOx technologies as well as the paper will present the operational experience in European countries where the technology has been operating for approx. 10-15 years. The experience is based on Ramboll’s experience with NOx control on advanced WtE plants in Europe. Technical SCR solutions will be discussed and specific technical obstacles and specific precautio...

Recovery of energy from MSW by combustion in Waste-to-Energy (WTE) plants reduces land filling and air/water emissions, and also lessens dependence on fossil fuels for power generation. The objective of this study was to assess the potential of gasification processes as an alternative to the combustion of MSW. Gasification uses a relatively small amount of oxygen or water vapor to convert the o...

Growing world population and increasing density are leading to waste production with biological amounting several billion tonnes annually. Together the need for renewable energy sources, waste-to-biogas conversion as a prime example of waste-to-energy technology represents facile way solving two problems simultaneously. This review aims address recent progress in field technology, which is late...

This paper describes the context, the basic assumptions and the main findings of a joint research project aimed at identifying the optimal breakdown between material recovery and energy recovery from municipal solid waste (MSW) in the framework of integrated waste management systems (IWMS). The project was carried out from 2007 to 2009 by five research groups at Politecnico di Milano, the Unive...

The size reduction of municipal solid waste (MSW) particles on the reverse acting traveling grate of a waste-to-energy (WTE) combustion chamber was estimated by means of a numerical model combining the particle size distributions (PSD) of MSW and combustion residues and the Shrinking Core Model (SCM). This new integrated model was used to simulate the particle behavior on the grate. During thei...

In many countries, waste management is increasingly geared towards a circular economy, aiming for sustainable society with less generation, fewer landfills, and higher rate of recycling. Waste-to-Energy (WtE) plants, which convert into heat energy, can contribute to the economy by utilizing types that cannot be recycled. Due varying quality sorting socio-economic conditions in individual region...
